摘要

王旭(2021)。多元线性回归下西沙群岛海域地貌异质性的分形特征地球科学研究，25(1)，41-48。DOI: https://doi.org/10.15446/esrj。基于西沙群岛水域地形具有明显的各向异性，利用多元线性表达式研究了西沙群岛水域地形的不均匀分形特征。采用多元线性回归分析方法提取非均质特征因子投影，得到西沙群岛水域的几何非均质特征。基于投影覆盖法研究了西沙群岛地貌的分形特征，测量了西沙群岛海域非各向同性体不规则度。实验结果表明，该方法可以有效地分析西沙群岛海域的非均匀分形特征。相应区域西沙群岛不同类型地貌的分形维数为高山区>，中山区>，盆地区>，反映了不同类型地貌表面粗糙度或复杂程度的差异。计算得到的分形维数有助于揭示不同发育阶段一般地貌特征的异质性。多元线性回归分析西沙群岛海域地貌异质性的分形特征
